You evolve a schema when you create a new version. Schema Registry tracks the changes made
to your schema, and stores each set of changes in a seperate version of the schema. When
multiple versions exist, you can select which version you want to use. Ensure that you
understand compatibility policies, as they determine how you can evolve your schemas.

Prerequesites

You have selected the Evolve checkbox when initially
adding the schema.

You have the schema you want to evolve saved to a file.

Steps

Expand the schema you want to edit and select the schema version from which you want
to evolve.

Click the pencil icon to open the Edit Version dialog.

Add a description of what has changed in this new version of the schema. You can view
the description in the Schema Registry UI to easily understand what has changed in each
version of the the schema so we recommend that you add as much detail as you can.
